摘要: 本研究以不同品种百香果为试验材料,测定了沃丰康育苗专用微生物菌剂对台农1号和钦果9号百香果扦插苗、钦果9号百香果嫁接苗根系生长和活力的影响;通过温室盆栽试验评价了单独施用复合微生物菌剂灌根宝、灌根宝与化学药剂精甲·咯·嘧菌联用以及土壤熏蒸后不同施用方式对百香果茎基腐病的防病促生效果。结果表明:台农1号扦插苗、钦果9号扦插苗和钦果9号嫁接苗用1000倍稀释的沃丰康菌剂灌根处理(50 mL/株)后,其地上部及根系长势均优于清水处理的果苗,根鲜重分别提高了45.5%、93.6%和72.0%,根系活力分别提高了129.8%、139.2%和110.3%。在百香果茎基腐病菌甘薯新赤壳Neocosmospora ipomoeae菌株B7和金色毛壳菌Arcopilus aureus菌株A28孢子悬浮液(均为1×107孢子/mL)与土壤混和(体积质量比为2:1:20)制成的病土中,灌根宝撒施于茎基部处理及灌根宝撒施联合精甲·咯·嘧菌灌根处理对百香果茎基腐病的防效均达100.0%。在菌株B7和A28固体接种物与土壤混和制成的病土中(质量比为2:1:20),使用棉隆(50 g/m2)进行土壤熏蒸处理的百香果苗的株高、根长和根鲜重均高于未熏蒸的处理,其中熏蒸后撒施灌根宝并浇灌1500倍精甲·咯·嘧菌稀释液处理的防病效果达85.4%。本研究表明,沃丰康育苗专用微生物菌剂对不同品种百香果苗均有明显促生作用,适合在百香果育苗期使用。对于病原菌数量多的种植土壤,棉隆熏蒸与化学杀菌剂精甲·咯·嘧菌和微生物菌剂灌根宝联合使用对百香果茎基腐病的防病促生效果最好。

Abstract: This study investigated the effects of Wofengkang, a special microbial agent for seedlings cultivation, on root growth and vitality of cutting seedlings of variety Tainong No. 1 and Qinguo No. 9 as well as grafted seedlings of variety Qinguo No. 9. Moreover, the efficacies of the microbial agent Guangenbao in suppressing basal stem rot disease of Tainong No. 1 seedlings as well as its effects on seedling growth were evaluated under different application methods during transplantation in the greenhouse, individually or co-applying with the chemical agent azoxystrobin+metalaxyl-M+fludioxonil, or application after soil fumigation. The results indicated that root drenching with Wofengkang microbial inoculant (1000-fold dilution, 50 mL/plant) significantly improved the shoot and root growth of passion fruit seedlings compared to the water control. For Tainong No. 1 cuttings, ‘Qinguo No. 9' cuttings, and ‘Qinguo No. 9' grafts increased by 45.5%, 93.6%, and 72.0%, respectively, and the root vitality increased by 129.8%, 139.2%, and 110.3%, respectively. In the diseased soil artificially inoculated with spore suspensions of Neocosmospora ipomoeae strain B7 (1×107 spores/mL) and Arcopilus aureus strain A28 (1×107 spores/mL) at a volume/weight ratio of 2:1:20, all treatments applied with Guangenbao or co-applied with azoxystrobin+metalaxyl-M+fludioxonil performed the best control efficacy of 100.0%. In the diseased soil artificially inoculated with solid pathogen inocula of strain B7 and A28 at the weight/weight ratio of 2:1:20, the passion fruit seedlings grown in dazomet-fumigated soil exhibited higher plant height, root length, and fresh root biomass in comparison with non-fumigated treatment. And co-application of azoxystrobin+metalaxyl-M+fludioxonil with Guangenbao after fumigation performed good control efficacy of 85.4%. The results demonstrated that Wofengkang agent promoted the seedlings growth of different passion fruit varieties, indicating that it can be recommended for application in seedling cultivation. As to the diseased soil with high amounts of pathogens, co-application of fungicide azoxystrobin+metalaxyl-M+fludioxonil with microbial agent Guangenbao after dazomet fumigation performed best on disease control plant growth promoting effects.
